All piano students, want to learn difficult pieces, that usually happen to be the nicest.
What would you think of a first year student that wants to play trascendental studies by Liszt?
I think is nonsense, unless you are a genious, maybe you could learn the notes, but that doesnt mean you play the piece, I can guarantee that. You should see piano learning as a long walk, each step takes you further, but if you suddenly jump, you will miss a lot of things you need to play well. Playing piano is not about playing notes, is much more complicated than that. The huge effort you are doing leaning that piece on your own, is not woth at all. Maybe it gives you the illusion of being a pianist, but is just an illusion. I agree with everybody, try to get a teacher, if is only once a month, even that will help you more than what you are doing now. It's up to you, of course, but learning piano is also about patience, among other things
